Description

[Technical Field]

[0001] The present invention is directed to devices, methods, systems, and apparatus for locating and removing hair or tattoos. [Background technology]

[0002] For hair removal, several methods and corresponding devices are known in the art, such as laser-based hair removal and intense pulsed light (IPL).

[0003] When skin is exposed to appropriate radiation, the radiation penetrates the skin. Depending on the absorption coefficient and wavelength of the radiation, most of the energy is absorbed by chromophores, which are then damaged. This damage is particularly severe when there is a large difference in absorption coefficient between the skin and the chromophores. The energy is absorbed by chromophores, which can be either endogenous in the tissue, such as melanin, hemoglobin, etc., or exogenous compounds, such as different colored tattoo inks.

[0004] By using radiation of certain wavelengths that are absorbed by the chromophore, damage can be substantially limited to the hair follicle or tattoo ink. Laser technology is known in the art for providing radiation of defined wavelengths.

[0005] The following documents describe the use of laser light or laser elements for hair removal:

[0006] US Patent No. 6,030,378(A) discloses a method of hair removal used primarily for cosmetic purposes, which involves the transdermal use of laser light having a wavelength that targets the sebum found within the hair follicle and covering the hair, heating the sebum so that heat is transferred first to the hair and root and then via conduction to the papilla and papilla blood vessels, thus destroying the hair by photothermolysis while avoiding significant damage to the surrounding skin or tissue.

[0007] U.S. Patent No. 6,666,856 (B2) discloses a hair removal device that includes a cooling surface that is used to contact the skin prior to exposure to tissue-damaging laser light passed from a radiation source through a recessed window. To create a gap between the window and the skin, the window is laterally offset from the cooling surface and spaced apart from the cooling surface in a direction away from the patient's skin. The windows preferably include both an inner window and an outer, user-replaceable window. The laser pulse duration is preferably selected according to the approximate diameter of the hair.

[0008] US Patent No. 7,029,469 (B2) discloses a method and apparatus for removing hair from living skin, which includes measuring the color of the area of ​​skin from which hair is to be removed with a colorimeter to obtain a representative color value, using the color value to select an optimal range of laser energy required to inactivate hair follicles in the area while minimizing any inflammatory response, and directing the optimal range of laser energy at the area of ​​skin to remove hair from the area.

[0009] U.S. Patent No. 7,108,690 (B1) discloses a hair removal device including a laser source, an adjustable laser beam manipulator for positioning the laser beam of the laser source at a target location on the skin to be treated, and an image sensor for detecting an image of the skin. The hair removal device further includes a control unit for determining the position and orientation of the hair to be removed on the skin and determining the target position of the laser beam according to the position and orientation of the hair. The control unit causes the laser beam manipulator to enter a state corresponding to the target position of the laser beam and activates the laser source when the laser beam manipulator reaches the state. Therefore, the hair removal device is suitable for use by inexperienced users and is particularly suitable for the consumer market. In certain embodiments, the control unit determines the target position of the laser beam at a location on the skin where an underlying hair root is present, resulting in destruction of the hair root, and the hair removal device is a hair removal device that removes hair for a relatively long period of time or even permanently. In another embodiment, the control unit determines a target position of the laser beam at a location on the skin where the hair emerges from the skin, resulting in the hair being burned off near the skin surface, and the hair removal device is a shaving device, thereby achieving a high level of skin smoothness.

[0010] Furthermore, the use of intense pulsed light is known in the art. Intense pulsed light hair removal works as described above, but because pulsed light is not a laser, it is typically not limited to a specific wavelength or narrow wavelength interval. Therefore, energy can be selectively applied to hair follicles and / or tattoo ink colors. However, these devices can be smaller and even handheld.

[0011] U.S. Patent Application Publication No. 20140236136(A1) discloses a device and method for hair removal treatment. The device includes a combination of two light sources, one IPL and the other incandescent or halogen. The two light sources are irradiated simultaneously or sequentially onto the treatment area. The present invention relates to a method for hair removal treatment, in which multiple light sources are combined together, including at least one pulsed arc lamp, and operated simultaneously or sequentially to treat selected skin areas. The incandescent light energy increases the overall skin temperature, while the arc lamp selectively ablates hair follicles with minimal collateral damage. Summary of the Invention

The laser diodes may include different semiconductor materials that determine the wavelength of the emitted beam. Each laser source may be configured with a different wavelength. In some embodiments, a processing component may control the laser system, and wavelengths may be selected based on targeting data. For example, if the target area is skin tissue with fair to tan skin tones and the target is medium to coarse dark hair, a 755 nm wavelength laser may be used. For fair to tan skin tones and dark, fine hair, a diode laser in the 800 nm to 810 nm range may be used.

The lens can be configured to be disposed between the laser system and the target region. In some embodiments, the two laser sources can have the same wavelength and can create a focal point on the optical axis. The focal region can include multiple focal points along the length of the optical axis of the lens.

The lens frame 39 may further be mounted on two X-direction bars 36. The lens frame 39 may also be configured to move between two Y-direction bars 33. The Y-direction motor 34 may be driven by a Y-direction spindle drive 34A. The Y-direction spindle drive 34A may further be facilitated by a Y-direction spindle nut 34B.

[0191] Reference signs and letters appearing between parentheses in the claims identify features described in the embodiments and shown in the accompanying drawings and are provided as an aid to the reader as examples of the claimed subject matter. The inclusion of such reference signs and letters should not be construed as imposing any limitations on the scope of the claims.

[0192] The term "at least one of a first option and a second option" is intended to mean either the first option or the second option, or the first option and the second option.

[0193] Whenever relative terms such as "about," "substantially," or "approximately" are used herein, such terms should be interpreted as including the exact terms as well. That is, for example, "substantially linear" should be interpreted as including "(exactly) linear."

[0194] Whenever steps are described above or in the appended claims, it should be noted that the order of steps described in this document may be accidental. That is, unless otherwise specified or clear to one skilled in the art, the order of steps described may be accidental. That is, when this document states, for example, that a method includes steps (A) and (B), this does not necessarily mean that step (A) precedes step (B), but it is also possible that step (A) is performed (at least partially) simultaneously with step (B), or that step (B) precedes step (A). Furthermore, when it is said that step (X) precedes another step (Z), this does not imply that there is no step between steps (X) and (Z). That is, a step (X) preceding step (Z) encompasses not only a situation in which step (X) is performed immediately before step (Z), but also a situation in which (X) is performed before one or more steps (Y1), ..., followed by step (Z). Corresponding considerations apply when terms such as "after" or "before" are used.
